Product Description
Outer spherical ball bearings are actually a variant of deep groove ball bearings, characterized by a spherical outer diameter surface on the outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat to achieve centering. Although its basic performance should be similar to that of deep groove ball bearings, due to the fact that this type of bearing is mostly used in rough machinery, the installation and positioning are not precise enough, the axis alignment between the shaft and the seat hole is misaligned, or the shaft is long and has large deflection, and the accuracy of the bearing itself is not high enough, some structures are also rough, so the actual performance of deep groove ball bearings of the same specifications is quite discounted.
Pillow block bearing
It is mainly used to bear radial and axial combined loads, mainly radial loads. Generally, it is not suitable to bear axial loads alone. This type of bearing can be separately installed with an inner ring (with a full set of rollers and retainers) and an outer ring. This type of bearing does not allow the shaft to tilt relative to the housing, as it will generate additional axial force under radial load. The size of the axial clearance of this type of bearing is closely related to its normal operation. When the axial clearance is too small, the temperature rise is relatively high; When the axial clearance is large, the bearing is prone to damage. Therefore, special attention should be paid to adjusting the axial clearance of the bearing during installation and operation. If necessary, pre interference installation can be used to increase the rigidity of the bearing.
A spherical bearing with a seat is a type of bearing unit that combines a rolling bearing with a bearing seat. Most outer spherical bearings have a spherical outer diameter and are installed together with imported bearing seats with spherical inner holes. They have various structural forms, good universality and interchangeability.
Application area
Outer spherical bearing is a commonly used type of rolling bearing, characterized by a spherical outer diameter surface on the outer ring, suitable for bearings in industrial machinery, mining and metallurgy, agricultural machinery, transportation systems, construction machinery, and other fields.
